Abstract

Pharmaceutical compositions containing certain imidazo(2,1-b)thiazoles, their physiologically acceptable acid addition- or quaternary ammonium salts, and a process for reducing blood sugar levels by the administration thereof.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A method for the reduction of the blood sugar level in a patient suffering from diabetes, which comprises administering to said patient an imidazo( 2,1-b)thiazole of the formula: ##STR11## wherein: A' is COOR" and R" is hydrogen or lower alkyl; C' is methyl, tert.-butyl or phenyl; and   D' is hydrogen or lower alkyl; or pharmaceutically acceptable acid salts thereof; in an amount effective for lowering the blood sugar level.     
     
     
       2. The method of claim 1, wherein the imidazo(2,1-b)thiazole is 3-methyl-imidazo(2,1-b)thiazole-6-carboxylic acid. 
     
     
       3. The method of claim 1, wherein the imidazo(2,1-b)thiazole is 2,3-dimethyl-imidazo(2,1-b)thiazole-6-carboxylic acid. 
     
     
       4. The method of claim 1, wherein the imidazo(2,1-b)thiazole is 2-ethyl-3-methyl-imidazo(2,1-b)thiazole-6-carboxylic acid. 
     
     
       5. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-methyl-6-carbomethoxy-imidazo(2,1-b)thiazole. 
     
     
       6. The method of claim 1, wherein the imidazo(2,1-b)thiazole is 3-methyl-6-carboethoxy-imidazo(2,1-b)thiazole. 
     
     
       7. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-methyl-6-carbopropoxy-imidazo(2,1-b)thiazole. 
     
     
       8. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-methyl-6-carboisopropoxy-imidazo(2,1-b)thiazole. 
     
     
       9. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-methyl-6-carbobutoxy-imidazo(2,1-b)thiazole. 
     
     
       10. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-methyl-6-carboisobutoxy-imidazo(2,1-b)thiazole. 
     
     
       11. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-methyl-6-sec.carbobutoxy-imidazo(2,1-b)thiazole. 
     
     
       12. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-t-butyl-6-carbomethoxy-imidazo(2,1-b)thiazole. 
     
     
       13. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 3-phenyl-6-carbomethoxy-imidazo(2,1-b)thiazole. 
     
     
       14. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2-propyl-6-carbomethoxy-imidazo(2,1-b)thiazole. 
     
     
       15. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2,3-dimethyl-6-carbomethoxy-imidazo(2,1-b)thiazole. 
     
     
       16. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2-ethyl-3-methyl-6-carbomethoxy-imidazo(2,1-b)thiazole. 
     
     
       17. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2-propyl-3-methyl-6-carboethoxy-imidazo(2,1-b)thiazole. 
     
     
       18. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2-butyl-3-methyl-6-carboethoxy-imidazo(2,1-b)thiazole. 
     
     
       19. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2-isoamyl-3-methyl-6-carboethoxy-imidazo(2,1-b)thiazole. 
     
     
       20. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2,3-dimethyl-6-carboethoxy-imidazo(2,1-b)thiazole. 
     
     
       21. The method of claim 1 wherein the imidazo(2,1-b)thiazole is 2-ethyl-3-methyl-6-carboethoxy-imidazo(2,1-b)thiazole. 
     
     
       22. A method for the reduction of the blood sugar level in a patient suffering from diabetes, which comprises administering to said patient 3-p-chlorophenyl-6-carbomethoxy-imidazo(2,1-b)thiazole or a pharmaceutically acceptable acid salt thereof, in an amount effective for lowering the blood sugar level.
